Application filed Ma'rli- 5, 1926. Serial No. 92,401;

c manufacture of such tie-plates is prohibitive', mainly on account ofthe expense involved in producing the inclined faces, also in providingmeans for holding such rolling member against vertical movement.

The object of this invention is 'to' provide a device of this characterwhich shall be simple in structure, eflicient in operation, and whichmay be economically manufactured and installed thus avoiding theabove-noted objectionable features.

The invention consists in certain novel" details of construction andarrangementjl by which the above objects are attained, to be hereinafterdescribed and'claimed.

The accompanying drawings form apart of this specification and show anapproved form of the invention.

Figure 1 is a plan view showing a portion of'a' railsupported upon andengaged with a tie-plate.

Figure 2 is a vertical section of the same parts, taken transversely ofthe rail, on the line 2-2 in Figure 1.

Figure 3 is a plan or top view of the rolling member alone on a largerscale than the preceding figures.

Figure 4 is a side elevation corresponding to Figure 3.

Similar reference numerals indicate the same parts in all the figures.

The rail is of standard type having the head 5, vertical web 6 andbasefianges and 8, supported on a tie-plate 9 and held in place thereonand to the tie, not shown, by spikes 10 in the usual or any approvedmanner.

On the upper face of the tie-plate, near one end, is a transverseabutment 11 extending parallel with and against which the outerbase-flange 7 is held against lateral movement outwardly. On the upperface of the tie-plate andoppositely disposed to the abutmeilt 11, is aridge 12 extending the full Width of the plate, and having a tees 1.3

which is p reseinted"v toward the inneradja-c ce'nt base-flange 8;. the.face 13 is plane, ea pendicujlar to the fat: of the ti'c plate', andparallel with the edge of the base-flange 8; The face 13" is formedby'undercutting the ridge: to produce an overhanging lip 17' ex tendingtoward the rail, anrl'the sameshaping operation produces a wide sha' owgroove 18 in the upper face of tl'i'e je p'l'a te iitcnd fully acrossthe latter andrealching from the face 13 of the ridge liito aline'beheatli and adjacent to the edge of the inner basefl'ainge 8.

The rolling memterir li'es'in tlie'groove 18 and is adapted to engagethe face'13and the'edgte of the base-flange 8,,and of anysh'apejad'aptedto increase in width as it is" moved forward bytliecree'pi'ng movement offtlie rail and is" preferaby elliptical inplan with t"e: main vportion of its peripheral edge perpendicular to itsbase and is, previded vvi h'ivertifcal corrugations or te etlt 1'63Theup'per and lower margins are chanrfere'd or beveled 'circunrferentially as I at 15 to avoid the formation of burrs orroughnesses on" its plane faces in the operation of producing theteeth-The: roller thus shaped is introduced in the parall sided spiacef'btween the face 13 of the ridg'e' "2 and edge of the wattage 8; it ispartially rotated to engage its periphery with those surfaces and insuch relation thereto as to be further partially rotated by the advancemovement of the rail in the direction indicated by the arrow in Figure1, causing the required frictional bite or pinching action to increaseas the angle of the major axis of the ellipse widens relatively to suchsurfaces, with the result that any further movement of the rail iseffectually resisted and stopped. As this movement is slight thedifference in length between the major and minor axes of the ellipse maybe correspondingly slight, so that the cramping action against thebase-flange 8 may be strongly induced by an easily rotatable nearlycylindrical roller The overhung lip 17 serves to hold the member 14;against escape by a vertical climbing movement, and is economicallyproduced by the same milling operation which produces the groove 18 andface 13.

By making the surface lfiiperpendicular to and parallel with therail-base the same tie plates will serve with the rails at both inboundand outbound tracks, it being only necessary to introduce the members 14with their axes in proper angular relation to the ridges and to thebase-flanges of the rails.

Parallelism of the surface 13 of the ridge and edge of the base-flange 8of the rail permits the introduction of two or more rolling members 14if desired.

The elliptical shape of the rotatable member effects a further importantadvantage in that the flatly curved sides offer surfaces of greatercontact area to the ridge and baseflange than is possible with a truecylindri cal form, thus insuring the strong frictional engagementrequired to wedge the rail-base between the ridge 12 and abutment 11 andhold the rail reliably against creeping. s

The groove 18 permits the rolling member 14 to be located at a lowerlevel relatively to the base-flange 8 and thus locates the base-flangeand parallel therewith, a groove extendlng from said surface to aline-beneath said inner base-flange and from'side to side of said plate,and a rolling member located in said groove in the space between saidsurface and edge of said inner base-flange, adapted to engagefrictionally with said surface and said edge, and to increase suchfrictional gripping action by the movement of said rail in onedirection.

In an anticreeping device, a tie-plate adapted to support a rail, anabutment on said plate adapted to lie against the outer base-flange ofsaid rail, a ridge on said plate adjacent to and separated from theinner base-flange of said'rail, said ridge having a vertical surfacepresented toward saidinner base-flange and parallel therewith, a grooveextending from said surface to a line beneath said inner base-flange andfrom side to side of said plate, and a vertically corrugated ellipticalrolling member locatedin said groove in the space between saidsurfaceand edge of said inner base-flange, adapted to engagefrictionally with said surface and edge. 1
